RELATED PATENT APPLICATION

This application claims the benefit of U.S. provisional patent application Ser. No. 62/566,976 filed on Oct. 2, 2017 by Thomas Earl Haines of Elizabeth, Colo., U.S. and Ronald Leslie Ferguson of Elizabeth, Colo., U.S.

TECHNICAL FIELD

The present invention is directed to an apparatus that enhances a user's agility in periodically manually conducting a pendulum type motion with a dynamic object that is tethered to a pair of manual handholds that the user grasps. More particularly, the present invention is a tethered weight that is affixed a pair of flexible tethers that are each grasped in each user's hand, wherein the user utilizes somewhat of a figure eight motion of their hands to swing the tethered variable weight in accordance with the user's hand motion. The tethered weight motion or movement can have varying cycle frequency and amplitude from the manual nature of the varying repetitive speed and varying force that the user can impart to the tethered weight and the changing positions of the user's torso position, thus changing up the agility skill required resulting in desired muscle confusion as opposed to a steady rhythmic hand/arm/torso frequency and amplitude.

BACKGROUND OF INVENTION

It is well recognized in the prior art the benefit of rhythmically manually engaging in agility enhancement, especially common in the fields of boxing and self-defense. However, if the rhythm becomes too steady over time, related to the frequency and amplitude of the tethered weight being consistent or nearly consistent, the agility benefit to the user becomes greatly reduced and the user's muscles become trained in a routine and do not improve their flexibility or agility. There is a movement afoot today that is termed “muscle confusion” that has shown that changing up one's agility enhancement routine results in better muscle tone and conditioning, such as in jogging—wherein a person would jog for so many miles at a steady pace-would achieve a minimal benefit, this as opposed to engaging in muscle confusion, which would have the jogger sprinting, walking, and jogging in a random way, this keeping the muscles in a dynamic state of (velocity & load) change (enhanced conditioning benefit) as opposed to a steady routine (minimal conditioning benefit).

Thus, this is the goal of the present invention in helping to create muscle confusion, due to the variable frequency and amplitude manually imparted to the tethered weight via the user's hands and the user's torso and leg movement, thus making the tethered weight movement path desirably unpredictable.

In the portable agility enhancement apparatus prior art in U.S. Patent No. 6,752,747 to Yu disclosed is a multi-directional swivel body builder, mainly comprising a moveable bent shank, two handles, two retaining springs and two end wheels, each end of said bent shank linking with a coil spring, a protection jacket covering said bent shank and said coil springs, characterized in that: a joint tube has a lock hole and a ring groove for receiving the retaining spring. The retaining spring in Yu has a turnover leave with a lock post fitting into the lock hole of the joint tube, the joint tube slides into a sleeve tube of the handle, the sleeve tube has a plurality of adjustable holes, after the joint tube slides in place in the sleeve tube, the lock post of the retaining spring will fit into one of the adjustable holes and a catch lug on an inner wall of the sleeve tube will enter the ring groove of the joint tube to disengage the lock post of the retaining spring. Thus permitting in Yu the handle to adjust and gain a proper bent angle, then the lock post fits into the proper adjustable hole and holds the angled handles that is accomplished with the adjustment; and the handle end connects to a lock shaft and an end wheel, when the end wheel is swayed, the bent shank begins self-rotation.

Continuing in the portable agility enhancement apparatus prior art in U.S. Pat. No. 7,828,704 to Hsieh, et al. disclosed is a combination limb and abdominal agility enhancement, comprising: a set of pivotally connected rod members including first and second main bodies which can be assembled and fixed to each other, each of the first and second main bodies having an extending rod, the two rods being able to be moved outward away from or moved inward closer to each other, and a handle being disposed at the end of each of the rods. Wherein in Hsieh, each of the first and second main bodies has a through hole and a groove disposed on the periphery of the through hole, and a post passes through the two through holes which are respectively covered by covers which are respectively fixed to the first and second main bodies by means of locking portions; two handles, each of which is pivotally disposed at an end thereof to the end of each of the two rods, so that the handles, when subjected to an external force, rotate at an angle about a longitudinal axis of the extending rod.

Further in Hsieh, a second torsional spring is disposed between each handle and the corresponding rod to bias against the rotation of the handles; and a first torsional spring, which is mounted around the post and disposed between the two rods of the set of pivotally connected rod members so as to normally maintain a fixed included angle between the two rods and provide an agility enhancement resistance when the two rods are moved outward away from or moved inward closer to each other by an external force. Wherein in Hsieh the end of each of the two rods is formed with a sub-rod, and the second torsional spring is mounted around the sub-rod on which a locking cap is securely mounted above the second torsional spring, wherein a locking hole is disposed on the sub-rod for the fixation of the locking cap, and wherein one end of the second torsional spring enters a first through hole preset on the rod, and the other end of the second torsional spring enters a second through hole preset on the handle.

Next in the portable agility enhancement apparatus art in U.S. Pat. No. 8,888,666 to Quader disclosed is a strength training apparatus comprising: an elastic headpiece constructed to recoil in response to being struck against a rigid surface; a handle mechanically coupled to the headpiece such that the recoil of the headpiece is transferred to the handle; and a centripetal stop at the distal end of the handle and disposed interior to the headpiece so as to couple the handle thereto and retain the headpiece thereon.

Moving onward in the portable agility enhancement apparatus prior art in U.S. Pat. No. 6,595,827 to Kirley, disclosed is a swinging toy intended for the purpose of recreation, physical and mental health, agility, and leisure purposes. Kirley includes a padded object and a cord with a hand or finger loop, wherein the object includes a central cavity that may selectively or permanently contain a substance. The substance in Kirley may include colored water, beads which may glow in the dark, chemiluminescent fluid, batteries together with a light, reflective material, e.g, tin foil, chemical compositions that alternate between colors or other such substances, or magnetically powered light sources. Further in Kirley, a decorative tail may be attached to the end of the object to enhance the user's enjoyment of the toy.

Next, in the portable agility enhancement apparatus prior art in United States Patent Application Publication Number 2013/0190145 to Kugielsky, disclosed is a dynamic weight training apparatus for improved calorie burning and muscle toning. The weight training apparatus in Kugielsky generally includes a pendulum mass suspended, e.g., via a flexible shaft, from a single handle or other securing mechanism. A user in Kugielsky swings the weight in a pendulum motion when exercising (walking, jogging, stationary, sitting or standing) providing for increased resistance. A flexible shaft in Kugielsky may advantageously dampen/reduce shock and strain associated with the pendulum motion.

What is needed is an agility enhancing apparatus that has a random unpredictability to the frequency and amplitude of the tethered changable weight movement that is created from the variability of the user's hands motion, plus movement of the user's torso and legs which in turn impart the variable frequency, amplitude, and load to a movement of the tethered weight, thus in turn creating the desirable “muscle confusion”.
